Specification of Letters Patent.

Patented May 11, 1915.

Application filed November 29, 1912. Serial No. 734,090.

To all whom it may concern:

Be it known that I, HAROLD T. SMITH, a citizen of the United States,residing at Willis, in the county of Brown and State of Kansas, haveinvented certain new and useful Improvements in Canvas Butters forBinders; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

My invention relates to a butter for grain harvesters, and has for itsprincipal object to provide a simple and efiicient device for eveninggrain delivered from an elevator onto a binding table, so that thestalks may reach the binder in proper position. In accomplishing thisobject I have provided the improved. details of structure hereinafterdescribed and illustrated in the accompanying drawings, wherein Figure 1is a perspective view'of portions of a harvester, particularlyillustrating the upper portion of the binding table and my improvedbutter. Fig. 11 is an inverted perspective showing a driving mechanismfor actuating the butter. Fig. 111 is a detail perspective of thebutter. Fig. IV is a longitudinal vertical section of same, showing partof the binder table.

Referring more in detail to the parts 1 designates a portion of theframe of a harvester of any ordinary construction comprising a tractiondrive wheel 2, elevator frame 3 and the usual elevator 4, which latterpreferably comprises the double aprons 5, one of which is run over ashaft 6 in the upper portion of the frame 3 and driven from a chain belt7 which receives its power from a shaft 8 connected through suitablegearing with the traction drive wheel 2. Converging upwardly toward theelevator frame 3 is the binder table 9, which also may be of anyordinary construction, the binding mechanism not being shown as it formsno part of the present invention.

The butter, which forms the subject matter of this application,comprises spaced top and bottom frame boards 10, of substantiallytriangular construction, the bases of which face forwardly relative tothe harvester and the bottom board being fixed rigidly to the bindingtable. The upper inner side 11 of each board 10 is comparatively shortand converges into the apex 12 near the upper portion of the bindingtable, The boards 10 are spaced by the axles 13, one of which isarranged at each corner of the board, and each of the axles carries aroller 11 over which a slatted apron 15 is adapted to travel when adriven roller is actuated. The rollers 14 are set in from the edges ofthe frame boards so that the apron travels wholly therebetween and theapron slats bear against the inner surface of the boards. One of theaxles, preferably that 'at the lower end of the butter, is slidably ofwhich inclose the ends of the axle and the base of which carries a pin19 which projects through a cross-bar 20 carried by the frame boards,and has a spring 21 surrounding same and bearing against the base of theyoke and the bar to act as an ordinary belt tightener. The upper axle 13extends through the binding table and carries a beveled gear wheel 22which meshes with a similar wheel 23 on a shaft 21 journaled in theunder side of the binding table and provided with a sprocket wheel 25which is connected with a sprocket wheel 26 on the elevator apron shaftby means of a chain 27 so that when the elevator is in operation thebutter is driven through the gearing described.

In using the device, the harvester is driven through the grain which isout, carried up the elevator and delivered to the binding table in theordinary manner. Owing to the fact that the head of the grain is heavierthan the stalk butts, the headed ends will, when delivered onto thebinding table, fall faster than the butt ends, so that the stalksdescend at an incline unless means is provided for straightening same.

With the binding table provided with my improvement, when the grain isdelivered onto the table and the head ends descended in advance of thebutt ends, the butt ends are caught by the butter apron so that thestalks are moved laterally across the binding table and the bottom endsadvanced to even the stalks before the latter reach the bindingmechanism.

Vith a butter of this character, there is no tendency to strike thegrain so that the stalks will be kicked from the table, and the actionis positive, as all of the grain must pass the butter to get to thebinding mechanism.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters-Patent, is

1. The combination with a binding table, of a butter comprising closedtriangular and parallel frame members having longitudinal slots thereinadjacent one of their apices, having apices directed inwardly over thetable, and having short, inwardly directed sides at their upper ends, ayoke slidably mounted between the frame members, a roller having a shaftmounted in the yoke and projected into the frame slots, rollersrevolubly mounted in the other apices of the frame members, and an apronrun over said rollers.

2. The combination with a binder table,

of a butter comprising closed triangular and parallel frame membershaving longitudinal slots therein adjacent one of their apices, havingapices directed inwardly over the table, and having short, inwardlydirected sides at their upper ends, a yoke slidably mounted between theframe members, a roller having a shaft mounted in the yoke and projectedinto the frame slots, an apertured bar for spacing said frame members, arod on said yoke slidably projected through the aperture in, said bar, aspring surrounding the rod and bearing against the bar and yoke, rollersrevolubly mounted in the other'apices of the frame members, and an apronrun over said rollers in close proximity to said frame members.

In testimony whereof I afliX my signature in presence of two witnesses.
